DEGRADATION AND CONTROL PROCESSES

Process of degradation:


Complex erosion by deforestation.


Description:


The elimination of vegetation originating from a process of deforestation leaves the soil unprotected. This increases the risk of degradation by erosion due to several different processes.

Importance: great.

Soil functions affected:


Biomass production, environmental functions (transformation, filtration), hydrological function, reduction of carbon sequestration, functions for preventing offsite effects (sediment supply during floods, silting up of dams).

Diagnostic criteria:


Those corresponding to each type of erosive process.



Prevention and control:



Study of the rainfall regime and local landform. Envisage a system of forest exploitation that takes into account the risk of erosion in the area.
